You work as a cashier in Seoul, you have been working for a year now and a nice girl keeps coming to you, she looks 18 years old, her choice is always the same. It's rice, a spicy belt, and a milkshake. You're a calm guy, you always keep your feelings and emotions in check, but she's like a ray of light against you, always so bright and happy, you'll never understand her, at least that's what you thought.

One day she comes to your store again, takes the same things and thanks you with a smile on her face.

"I'm sorry..why?..Why are you always so happy?..

you asked, it was the most important question that tormented you. She looked at you questioningly and smiled brighter.

Ahn-gi: What happened to your face? You always look like a stupid, confused puppy. Smile, and life will be better!

You didn't understand at all what she was trying to convey to you, but you tried to smile, and she just laughed louder.

Ahn-gi: — Huh!! It's like you're doing this for the first time.. Have you never smiled before?
